Application filed. December 20, 1920.

To all whom it may concern Be it known that l, LEONARD Roan-RT Pos- OHADEL, a citizen of the United States, and a resident of the city of Milwaukee, in the county of Milwaukee and State of Viscousin, have invented a new and useful improvement in Refrigerating Apparatus, of which the following is a full, clear, and exact description.

My invention relates to improvements in refrigerating systems, and it consists in the combinations, constructions and arrangements herein described and claimed.

An object of my invention is to provide a system by means of which cooling of refrigerators, storage rooms and the like may be accomplished without the use of ice.

A further object of my invention is to provide a refrigeration system which can be economically maintained and operated due to the fact that use is made of cold water, such as that of a city water distributing system, the water first being run into water jackets or pipes connected with the cooling room or refrigerator whenever the faucets, hydrant or other means of discharge are opened.

A further object of my invention is to provide a. refrigeration system which has no movable working parts and which is operated whenever water is drawn from the water system.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claim.

My invention is illustrated in the accompanying drawings, forming part of this application, in which Figure 1 is a sectional view of a portion of a house showing my improved system as applied to a refrigerator,

Figure 2 is an enlarged vertical section through one embodiment of a refrigerator used in my system, and

Figure 3 is a section along the line 3-3 of Figure 2.

As stated before, my invention may be applied to coolin rooms or refrigerators. 1n the drawings fhave shown the invention as applied to a refrigerator. The latter has an outer casing 6. Within the casing and spaced from the outer walls thereof is a; water jacket having exterior walls 8 and interior walls 7. The space between the Serial No. 431,941.

outer wall 8 of the water jacket and the casing 6 is packed with heat insulating material 9, such as wool felt or the like. Within the refrigerator are disposed shelves 1O spaced so as to form compartments. One or more cooling pipes 11 may extend through these compartments for connecting different portions of the rater 'acket so as to permit the fio-wof cold water through the pipes if desired. The upper portion of the water jacket communicates by means of a discharge pipe 12 with a pipe 13 leading to the faucets such as that shown at 1 1, or to ahot water heater 1 1 etc. in Figure 1. The lower portion of the water jacket communicates by means of a pipe 15 with the city water mains, the usual water meter 16 being disposed so as. to register the amount of water taken from the main.

Underneath the bottom of the upper portion of the water jacket, 1 preferably place drip pans 1? which connect by means of a drain pipe 18 with the lower portion of the refrigerator. The lat-ter is drained by means of a pipe 19, a branch pipe 20 communicat ing therewith and draining off any moisture that may have accumulated in the space between the casing and the water jacket. 1n the bottom of the refrigerator are preferably placed floor grates 21 on which articles to be. cooled may be placed, thus leaving a free space for drainage of moisture which may collect within the refrigerator or be conveyer to the bottom by the drain pipe 18.

In the upper left hand corner of Figure 2, 1 have shown an ice chamber 22 in which ice may be placed if it is desired to cool the refrigerator below the temperature which would result from the water alone. A drain pipe 23 leads to the drain pipe 19.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. As stated, the water is piped from the main, not shown, and may be measured by the meter 16. When" any tap or faucet such as that shown at 1 1 is opened, the water is drawn from the main and passes upwardly through the pipe 15, thence through the water jacket and by pipes 12 and 13 out at the open faucet. The constant use of the water faucets throughout the building maintains a flow of cold water through the water jacket.

In very hot midsummer, it may be desiras an auxiliary cooling means in the able to use ice and this may oe done by placing it compartment- 22 as stated.

It will be seen that the operation of the refrigerator is: nm-int-ained by the drawing off of Water by occupants of the building. It is moreover, operated Without cost, since the Water which cools the refrigerator is used in the ordinary manner and is not wasted Water.

In Figure 73 I have shown means by which access is permitted to the interior of the cook ing Chlinhdi through t '0 doors These doors are hinged at and are provided With-insniatim walls 26. The doors are set into the casino 6 in such a inizrmmas to form heat retaining Wail portions when the doors are closed.

I claim:

A refrigerating apparatus comprising a casing having insulated Walls, a Water jacket disposed within said casing and having top, bottom and side portions in communication, the space between the side portions and the top and-bottom portions of the Water jac at constituting a storage chamber, a drip pan disposedwithin said storage chamber near the top port-ion thereof, cooling pipes extending; from the bottom of said Water jacket through said chamber and. said drip pan, and communicating with the top of the water jacket, a drain pipe for said drip pan disposed interioriy of said coolingnchamben the top of the bottom portion of: the Water jacket constituting av bottom for said cooling chamber, and a second drain pipe extending: through the bottom portion of the water jacket and communicating; with the interior of said cooling chamber.
